The Quest for the Most Spherical Bubble [PDF]

open access: yes, 2013
We describe a recently realized experiment producing the most spherical cavitation bubbles today. The bubbles grow inside a liquid from a point-plasma generated by a nanosecond laser pulse. Unlike in previous studies, the laser is focussed by a parabolic

Measures of Human Position Sense Do Not Always Include Contributions From Peripheral Sensory Receptors

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 5, March 2026.
This is a review of measurements of human position sense using three different methods. When measured by two‐arm matching or one‐arm pointing, evidence for participation of muscle spindles was present. For repositioning, a method based on memory, no evidence for spindle involvement emerged and the process appeared to operate entirely centrally.

Asymptotic structure of $\mathcal{N}=2$ supergravity in 3D: extended super-BMS$_3$ and nonlinear energy bounds

open access: yes, 2017
The asymptotically flat structure of $\mathcal{N}=(2,0)$ supergravity in three spacetime dimensions is explored. The asymptotic symmetries are spanned by an extension of the super-BMS$_3$ algebra, with two independent $\hat{u}(1)$ currents of electric ...

Sweat evaporation in humans: A molecular and thermodynamic perspective

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 643-652, 1 March 2026.
Abstract Evaporative heat loss through sweating is essential for maintaining thermal balance in humans, particularly during exercise or in hot environments. Although the physiological mechanisms regulating sweat production and skin blood flow are well documented, the molecular processes underpinning sweat evaporation are less often considered.

Repeated Changes to the Gravitational Field Negatively Affect the Serum Concentration of Select Growth Factors and Cytokines

open access: yesFrontiers in Physiology, 2019
Space flights, some physical activities, and extreme sports can greatly alter the gravitational forces experienced by the body. Being a deviation from the constant pull of Earth, these alterations can be considered gravitational stress and have the ...

Toxicity of lunar dust

open access: yes, 2012
The formation, composition and physical properties of lunar dust are incompletely characterised with regard to human health. While the physical and chemical determinants of dust toxicity for materials such as asbestos, quartz, volcanic ashes and urban ...

Microfluidic platform for electrophysiological studies on Xenopus laevis oocytes under varying gravity levels [PDF]

open access: yes, 2011
Voltage clamp measurements reveal important insights into the activity of membrane ion channels. While conventional voltage clamp systems are available for laboratory studies, these instruments are generally unsuitable for more rugged operating ...

Development of an adaptive meshing upper bound limit analysis method for large deformation axisymmetric geotechnical problems

open access: yesScientific Reports
This research introduces the development of a sequential limit analysis (SLA) method in OPTUM. The plane-strain analysis capability of the original SLA has been extended to encompass both plane-strain and axis-symmetric problems, and the usability has ...
